The PHP parameter
allow_url_fopen has been disabled in PHP across our web hosting services as a security measure.
allow_url_fopen allows PHP's file functions to retrieve data from remote locations such as an FTP server or website which can lead to code injection vulnerabilities. Typically these code injection vulnerabilities occur from improper input filtering when passing user-provided data to PHP functions. Disabling this function helps considerably in stopping your site from being compromised, as well as help prevent the unauthorised use of our servers for abusive or malicious purposes.
